i am trying to connect google apps ( google sheet , google docs , google drive ) to n8n self hosted on my pc ( tried both tunnel and non tunnel version)
when i tried to connect to n8n it showed me this problem
For this i searched the n8n forum and fixed it too using this response strong text
But after when i fixed the O Auth problem and connected the google account with n8n it is showing error 504 , connection timeout for both n8n tunnel and normal , by reading this post
This normally means your Google app is not correctly configured, I would avoid using the tunnel and use a reverse proxy or a different tunnel service like ngrok or cloudflared.
You may need to add your email to the allowed testers for your google app.
this is what i got after adding the emails to allowed testers list. i got the options to allow permission to my google account but then it keeps on loading until it times out
Yes, by exposing your n8n instance directly to the internet. As you are hosting your instance locally, it is better to use docker, as it will be run in the isolated container and not directly on your PC. Plus You’ll need to configure your router to forward a port you will use for webhook (443 or other). Plus you’ll need to get a Let’s Encrypt certificate (free) for the n8n to work via SSL.
